THOMAS" GORMAN, OF WARREN, RHODE ISLAND, ASSIGNOR OF ONE-l-IALF TO FRANKH. BROWN, OF WARWICK, RI-IODE ISLAND.

SPlNDLE-SUPPQRT.

SPECIFICATION forming part of Letters Patent No. 567,973, datedSeptember 22, 1896.

Application filed June 12, 1893.

To all whom it may concern.-

Be it known that I, THOMAS GORMAN, of IVarren, in the county of Bristoland State of Rhode Island, have invented certain new and 5 usefulImprovements in Spindle-Supports; and I do hereby declare the followingspecification, taken in connection with the accompanying drawings,forming a part of the same, to be a full, clear, and exact descriptionthereof.

The present invention relates to the manner of supporting the spindlesof spinningmachines; and it consists, primarily, in the combination,with bolster and step rails, of a bolster-bearing loosely mounted in thebolster-rail, a separate step-bearing fixed in the step-rail, and aspindle supported in said bearings with its whirl above both of saidbearings.

The invention further consists in certain combinations and arrangementsof parts hereinafter described.

Referring to the drawings, Figure 1 represents a front elevation, partlyin section, of bolter and step rails with two spindles mounted thereon.Fig. 2 is a top view of the same.- Fig. 3 is a transverse section on theline 0c of Fig. 2. Fig. 4 is a top view, and Fig. 5 a front elevation,of the bolster-bearings.

In the drawings I have shown my invention as applied to aspinning-machine in which, while two separate rails are employed, theupper or bolster rail is supported upon the lower or step rail, and onlythe latter rail is but a single line of brackets for supporting bothrails; but my invention may be employed, if desired, in a machine inwhich the bolster and step rails are supported upon separate lines ofbrackets and each rail thus secured directly to the frame.

The lower or step railA (shown in the drawings) is to be secured to theframe of a spinning-machine by means of supporting-brackets in the usualmanner. This step-rail may be of any desired or convenient length tocontain any desired number of spindles. I prefer to construct saidstep-rail in the form of a trough inclosed at the ends, sides, and bottom, in order that it may serve as an oildirectly secured to the frame,thus requiring $e1'ial No. 477,261. (No model) receptacle for all of thespindles mounted thereon.

, The upper or bolster rail B is supported upon the lower or step rail,and when said step-rail is constructed in the form of atrough 5 5 i thebolster-rail is preferably constructed to fit within said step-rail, asshown in the drawings. In such case the step-rail is preferably providedwith an offset or ledge a at each end, upon which ledges the ends of thebolster-rail rest, as shown in Fig. 1. The bolsters b are fitted looselyin the bolster-rail and so as to have a certain amount of lateral playtherein. Each bolster b is provided at its upper end with projectinglugs 19, adapted to enter and engage with a longitudinal groove 0,formed in the upper surface of the bolsterrail, as shown in Figs. 1 and2, whereby the bolster is prevented from turning with the spindle. Ifdesired, also, said projecting lugs b may serve as the means forsupporting the bolster vertically in the rail,

The bottom of the bolster-rail B is preferably cut away upon each sideof the bolster, as at y y, Fig. 3, so that only the central longitudinalportion of the bolster-rail is the full depth of the bolster, and sothat the receptacle formed by the step-rail A may be filled with oil toa level above the lower ends of the bolster.

Transverse holes d d are made in the downwardly-projecting portion ofthe bolster-rail, which said holes communicate with corresponding holesin the side walls of the bolsters, all as shown in Fig. 3, and by meansof 85 which the oil may be conducted to the spindle to lubricate thebolster-bearings. This cutting away of the bolster-rail and theformation of the oil-passages referred to, however, are not necessary,as the bolster-bear- 0 in gs may be properly lubricated by the suckingaction induced by the high revolution of the spindle, which, as is wellknown, will operate to draw up from the receptacle a sufficient quantityof oil between the bolster and 5 the spindle to properly lubricate thebolsterbearings. V

The steps 3 are firmly secured in the steprail A, and when thereceptacle formed by the step-rail is filled with oil the step-bearings10o will be immersed in the oil and will thus be thoroughly lubricated.

The spindle O is provided with the usualwhirl e, which said whirl islocated above both the bolster and step bearings and preferably only ashort distance above the upper end of the bolster-bearin g, as shown inthe drawings.

\Vith the combination and arrangement of parts above described, that is,with separate bolster and step bearings the bolster-bearing being loosein its supporting-rail and the step-bearing being fixed in itssupportingrail, and wit-h the spindle supported in said bearings, withits Whirl located above both of the bearings, a high speed of revolutionmay be obtained Without chattering, while the location of the whirlabove both bearings permits the spindle to be removed when desired withthe same facility as in a single-rail machine in which a combinedbolster and step and a sleeve whirl spindle are employed. Moreover, byemploying the construction and arrangement of rails shown in thedrawings, in which the'upper or bolster rail is supported upon the loweror step rail and in which only the step-rail requires to be directlysecured to the frame, thus requiring only a single line of brackets forsupporting both rails, the invention may be readily applied to suchsingle-rail machines by simply substituting the double rail withseparate bearings for the single rail and combined bolster and stepbearings of said machine.

l/Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination of a step-rail, a stepbearing fixed in saidstep-rail, a bolster-rail, a bolster-bearin g loosely mounted in saidbolster-rail, and a spindle supported in said bearings with its whirllocated above both of said bearings, substantially as described.

2. The combination of a step-rail, a stepbearing fixed in saidstep-rail, a bolster-rail,

a bolster loosely mounted in said bolster-rail, said bolster beingprovided at or near its upper end with one or more lugs or projectionsby means of which said bolster may be supported vertically in saidbolster-rail, and a spindle supported in said bearings with its whirllocated above both of said" bearings, substantially as described.

3. The combination of a step-rail, a stepbearing fixed in saidstep-rail, a bolster-rail provided with a groove or recess in its upperface, a bolster-bearing loosely mounted in said bolster-rail, saidbolster-bearing being provided at or near its upper end with one or morelugs or projections adapted to enter said recess in the bolster-rail toprevent the bolster from turning in said rail, and a spindle supportedin said bearings with its whirl located above both of said bearings,substantially as described.

4. The combination of a step-rail adapted to be secured to the frame ofa spinning-machine, a step-bearing fixed in said step-rail, abolster-rail supported by said step-rail, a bolster-bearing looselymounted in said bolster-rail, and a spindle supported in said bearingswith its whirl located above both of said bearings, substantially asdescribed.

5. The combination of a step-rail adapted to be secured to the frame ofa spinning-machine, said step-rail being constructed in the form of atrough to form an oil-receptacle, a step-bearing fixed in saidstep-rail, a bolsterrail supported by said step-rail, a bolsterbearingloosely mounted in said bolster-rail, and a spindle supported in saidbearings with its whirl located above both of said bearings,substantially as described.
